METHOD OF MAKING LEAD GAMES.

This invention relates tothe method of decorating and finishing leadcames wherein it is desired toprovide a lead came of an artistic design.v I

The method includes the applying of forming different decorativesurfaces on the cames in a. simple and effective manner by changing themaster patterns.

A further object of the invention resides in finishing and forming camesin a manner so as to draw out the came body and at the same time impressinto the surface thereof such decorative designs as to provide a veryattractive and desirable came which is used for leaded glass windowsandthe like. My

invent-ion is designed to carry out the meth-' od in an economical,simple and practical manner, permitting the formation of the cames withsuch a decorative facing over the entire outer surface of the same asmay be desired. The lead cames are of a soft nature and are readilyreceptive to impressingdesigns into the surface of the same, and mymethod is carried out in making the cames in a manner so as tofacilitate the accomplishing of the method without extra operation andexpense. V

' These features, together with other objects and details of thecarrying out of the method will be more fully and clearly set forth inthe specification and claims. To facilitate the clear understanding ofthe carrying out of my method I have chosen to illustrate in thedrawings a simple machine designed to make the cames.

Figure machine.

Figure 2 is a plan view of the same. I Figure 3 is a side elevation ofthe same. Figure 4 is a diagrammatic s1de view. Figure 5 illustrates aportion of the came before it has been finished by my method. Figure 6illustrates a portion of the came as it would appear when finished by mymethod.

In carrying out my method the lead came such as A illustrated in Figure5 is in its ordinary drawn state as it appears after it comes from theextrusion machine, and the came A illustrated in Figure 5 is designedwith a center steel reinforcing member 10 which is placed into theopening designed to receive the flat bar-like steel member. This openingis formed in the came as the same comes through the extrusion machineand the steel band is inserted within the 1 illustrates a front view ofthis 7 is made of soft or comparatively soft 14 and 15 are supported inthe side 16 of the forming machine B.

The machine B is erating pulley 17 which is adapted to drive the shaft18, which in turn drives the gear 19, positioned on one side of themachine B. The gear 19 meshes with the gear 20 which operates the shaft21 and drives the gear 22 on the opposite side of the machine to thegears 19 and 20., The gear 22 meshes with the gear 23,' While the gear23 is in mesh with the gear 24. The. gears 23 and 24 are secured to andadapted to operate the shafts 14 and 15, respectively.

The forming wheels 12 and 13 are removably 'or replacably held on theshafts 14 in an ordinary well known manner, the detail of which is notillustrated in the drawings, so that different forming wheels may beemployed in the carrying out of my method. Each of the wheels 12 and 13are formed wlth an inner surface 25 which is of a design, decorationv orshape so as to provide the desired shape and design to the outer surfaceof the came A adapted to be passed through the'machine B.

The machine B is provided with a pair of guide wheels 26 which aresupported by the bifurcated brackets 27 ina manner so as to hold the'wheels diametrically opposite eachother and to cause the surface of thewheels 26 to engage the shank 28 of the came A together and at the sametime firmly grip the came on the shank while the came is passing throughthe machine B. The width of the guide wheels 26 is such as to freely fitthe glass recesses or channels 29 formed in the side of'the came A, asillustrated in the diagrammatic illustration in Figure 4,

and as would be apparent from the front view in Figure 1. In fact, theguide wheels fit the recesses or channels 29 closely so that as the cameA passes through the forming rollers 12 and 13 the material of the cameis squeezed closely against the wheels 26 in a manner to squeeze theshank provided with an op- .and the serrated surface of the wheels 26 iscaused to bite into the shank 28 to prov1de a serrated inner surface" 30to the shank 28 and at the same time squeezing the body of the came Afirmly-against the steel rib 10 from all sides to form the came of thedesired cross sectional shape vand to' impress into the surface thereofthe decorative finish such as 32, illustrated in Figure 6. Thisdecorative surface may be of the same design and nature as thedecorative surfaces on the Wheels 12 and 13, and thus I provide a methodof making cames for leaded gl-ass windowsof a most desirablenature,having a design adapted to be attractive and at the same, timefacilitate the better making of'the came itself.

Theplain' unfinished design of the came is illustrated in Figure Whllthe'finished drawn out came wllidllahfls been reworked with the desiredouterfdesi'gn orl'finish is clearly illustrated inFigurc 6., By changingthe wheels 12 and 13'tosubstitutesvheels with adiiferent surface design,I can'make many differentdesiigns by passing the same througlrtheforming machine BI Thus in "carrying out my method therough unfinishedcame which comes from the extrusionma'chine' is adapted to bepassed'through the forming machine B wherein theidesired design orconfiguration is pressed and formed into'the came body; stretching the.came out as it passes through this forming process and at the same timeproviding a finished" came-much to be preferred over theordinarilyextrudedcame.

My 'method consists in' placing the ex truded, came in positionffto beengaged on practically all sides thereof'and then draivii ng the sameout to fern/ 11a finished came with a decorative or configured outerface and providinga finished came-to the'desi'red' 'slze and nature withan outer decorative facef The method is simple yet'v'ery effec- I claim:

tive'i'n providing a finished-came with practic'ally little 'or no extracostsin the formation of the same as it is necessary to form the :cameabout the. reinforcing rib 10 in this construction and even Without therib lOriti is necessary that the came be formed of the desired size andshape so that in passing there-me into the decorative forming rollers 12and 13 I provide a method of making and forming the same which 'isverydesirable." My method has been successfully carried out in making cameswith a hammered desi 'n, a rough cast design havmg a very roughenedouter surface, a

frosted design and many 4 other attractive designs to the outer surfaceand formation ofthec'ame.

In accordance Withthe patent statutes I have described the principles ofoperation of my'method'a'nd While I have illustrated means of carryingout the method, I desire to have it understood that this is'onlysuggestive and thatthe method can be carried I stantially their'centralportionsby' a Web c'ompris'ingpassing the came through rotary 'die meansacting'upon the outer surfaces of said flangesto ornament thesame and atthe sametime passing the web. of the came through rotaryf means'disposed at right angles to said die means to serrate both surfaces ofsaid-web and force theiinaterial of said Web about a reinforcing meanstherein.
